Definitions
- the invention relates to a sintered shift sleeve carrier according to the preamble of the main claim.
- a sintered shift sleeve carrier To provide, which is constructed in one piece and no mechanical processing for the manufacture of the supports for the presynchronous compression springs.
- each presynchronous compression spring support is made of one each in the sintering process simultaneously with the shift sleeve carrier manufactured centering projection of the shift sleeve carrier in the radial direction consists of the associated presynchronous compression spring on its inner diameter centered.
- a shift sleeve carrier according to the invention advantageously has no inserts.
- An advantageous embodiment of the invention provides that the parting plane the sintering tool in the middle through the centering projection of the shift sleeve carrier runs. This means that it can be manufactured without subsequent processing possible. This leads to a cost reduction and the transferable moment is increased.
- a preferred embodiment of the invention provides that the centering projection has an undercut that is designed so that the presynchronous compression spring can be snapped into this with one gear.
- the parts can be captively secured, for example by machines, be preassembled and the mass of the presynchronous compression spring decoupled with respect to centrifugal force. This is the mass influence minimized to the shifting force at different speeds.
- FIG. 1 shows a presynchronous compression spring 1 and its supports on a sintered shift sleeve carrier 2 at its radially inward end.
- the sintered shift sleeve carrier 2 has a cam-like projection 3, formed in one piece with the sintered shift sleeve carrier, which extends into the presynchronous compression spring 1 and fixes this to the inside diameter in the radial and axial direction.
- the parting plane of the sintering tool runs in the drawing plane so that manufacturing without subsequent processing is possible.
- FIG. 2 shows an additional modification of the embodiment according to FIG. 1, in which the presynchronous compression spring 1 is better fixed in the radial direction.
- the cam-like projection 3 has an undercut 4 on the cam base which can be removed from the sintering tool and into which the presynchronous compression spring 1 is locked with its first gear.
- the presynchronous compression spring 1 can be preassembled in a captive manner on the sintered shift sleeve carrier 2.
- the mass of the presynchronous compression spring is decoupled with regard to the centrifugal force effect, as a result of which the influence of mass on the switching force is minimized at different speeds.
